This invention-relates to improvements in button-making machines, andhas particular reference to a foot press mechanism therefor.

I An object of theinvention is to provide an improved mechanism ofsimple and practical construction by means ofwhlchamaxlmumpressure uponthe movable die of the machine will be obtainedand which mechanism maybeadjusted to regulate the effective movement of said die so that buttonsof H a button while the'upward movement of the different thicknesses maybe produced.

Another object isto utilize the support for the pressure mechanism as ameans to which a art of a button ejector device maybe ad ustablyconnected and supported for pro er ejectiontof the button from the die.T ie above and other objects will appear more clearl from the followingdetail description, w on taken in connectlon with the accompanyindrawing, which illustrates a preferredem I In the draw'ings 3 v 1 vFigure 11s a front elevation, partly in sec tion,-of. the machineconstructed in accordance with the invention;

Figure 2 is a fragmentary of the machine, partly broken awayan shown insection; and u v p Figure 3 is a 'sectionalview taken on the line 3 -3of Figure 1. i

The machine'of the present invention is capable of being support 5, suchas a table orthe like, and consists of upper and lowerframe members I 6and 7 connectedby the standards 8. bracket'9 is secured to the lower;member 7 and is utilized to support the foot operative ,treadlel0rpivoted to the .bracketat 11, the operative position of the treadlebeingshown in full lines in Figure 2. It is desirable to limit themovement of the *treadle to its operative position for a purpose 'whichwill P1 to, this end there is provided a laterally extending frame 12preferably extending from the support 5, said frame. consisting of apair-of parallel rods connected at their outer ends by a cross piece 13.A sliding abutment 14 is carried between said rods and maybe adjustedlon itudinally thereof by -a screw 15 having t readed engagement with rthe cross piece 13. The abutmentil l is mounted side elevation in thepath of movement of the lower end of odiment of the inventive I idea.

mounted upon a suitableear in the courseof the description and thetreadle 10 so that the latter will strike against the abutment as shownin Figure 2 when thesame is operated. r i

.Slidable vertically uponthe standards 8 is a plunger 16, the movementof which is controlled by the operation of the treadle 10 throu h themedium of a mechanism which will ater be described. The downwardmovement of the plunger 16 is utilized to control the operation of thedie in forming plunger produces theejection of the'butt'on from the dietThe die-consists of the upper and lower dieimembers' l7 and 18, thelatter of which .is mounted in a base plate 19secured to the framemember 7. The upper die member 17 slidable in a holder 20, the shank'21.of which is fitted within an openin 22 formed in'the plunger 16 andremova ly secured in position thereinfin any desired manner asby a screw23 extending laterally into the plunger 16 and engageable withsaid-shank. Theholder 20 also carries a cutter 24 therein in which thedie member 17 is also "movable and this cutter is held in position inthe holder by a screw 25., Posid tioned directly below the holder and cutterv is a material-supporting plate "26 having an openin therein forreceiving the u per-end of the owcr die member 18whentY1e die is in itsoperative position, as shown in F' 055" 1. This plate 26 isyieldablysuppor by springs 27 and normally the upper surface of, theplate is positioned slight othermaterial ofwhich the button is to bemade is laid upon the plate 26 directly below the upper die member 17and the cutter 24 so that when the latter two members are y'above the iupper end of the member '18'. With the" plunger-16 raised a sheet-ofcelluloid or forced downwardly with the plunger 16 the cutter will firstengage the sheet of material and .cut therefrom the button 28. In, so

and rce the same downwardly against the tension of the springs 28. Themolding surface of the up erdie member 17 comes in: contact with t eupper surface of the button 28'and thus molds the same into the doingthe cutter will'engage'the plate 26 desired configuration andsimultaneously a pair of hole-forming points or needles 29 supportedwithin the vmember 17 by a rod 30 are caused to penetrate the button 28to form openings in the center thereof. It will, of course, beunderstood that more than two of the points 29 maybe employed, ifdesired. The points 29 are removably held within the member 17 by therod 30 and a ferrule 31 mounted over the lower end of said rod. 7

After the cutting and molding operation of the button the plunger 16ispermitted to rise and in so doing the upper die member 17 is projecteddownwardly to eject the button 28 from within the lower end of thecutter 24, the plate 26 at the same time returning to its normalposition so that the remainder of the piece of material from which thebutton has been cut may be quickly removed from the plate "26 andanother piece of material placed imposition thereon. The means forcausing the ejection of the button consists of an ejector devicecomprising a disk 32 mounted within the opening 22 above the upper endof the shank 21 and having pins 33 depending therefrom and extendingthrough said shank so as to rest uponthe upper end of the member 17. Asthe plunger 16 rises the disk 32 comes in contact with the lower end ofan ejector operating rod 34, the mounting for which will later bedescribed in detail. This contact forces the ejector device andconsequentlythe die member 1? downwardly relative to the cutter 24 andneedles 29 so that the button. 28 will be ejected from the cutter memberand needles, the member 17 remaining in its projected position until thesame again engages a sheet of material upon the succeeding downwardmovement of the plunger 16. 1

The mechanism for the application of pressure to the plunger 16, theactuation of which is controlled by the treadle 10,. will now bedescribed. This mechanism is in the form of aftoggle constructionconsisting of a pair of upper arms 35 pivotally mounted at their upperends upon the trunnions of a bearing block 36 and each having a pivotpin 37 extending through its lower forked end so as to pivotally connectthe upper end of a lower arm 38 thereto, the lower end ofeach of saidarms 38 being in turn pivotally connected to the plunger 16 by means ofthe shackles 39. Each of the pins 37 has connected thereto the forkedend of a link 40, the other end of which is loosely mounted upon a pin41 carried by the upper extremity of the treadle 10. Through thisconnection of the arms 35 and 38 with the treadle,-it will beapparentwhen the upper extremity of the latter is raised, as shown indotted. lines in Figure 2, the pivotal connections 37 between said armswill be moved laterally so as to throw the arms out of verticalalignment and thus permit the plunger 16 to be ol vated, it beingunderstood that the trunnions of the bearing block 36 form a fixed pointrelative to which the arms move. When the treadle 10 is thrown to itsopera tive position the pivot 41 is lowered and the links40 cause thearms 35 and 38 to assume vertically "aligned positions with the resultthat the plunger 16 is forced downwardly the necessary distance toproduce the button forming operation. In thus operating the plunger careshould be taken that'the extremity of the downward movement of the pivot41 does not pass below a horizontal line connecting the center of saidpivot with the pivots 37 and it is for this purpose that the movement ofthe treadle 10 islimited and made adjustable by the abutment 14.

It sometimes occurs that difierent'sized, dies-are employed inconnection with the 8 machine which necessitates the regulation of themovement of theplunger, 16, .thisbeing accomplished through anadjustment of the operating mechanism for the plunger, and particularlythe bearing 36'. thereof.

For this purpose the upper framemembe'r'6 is provided with an opening 42through whichan adjusting screw 43 extends. i This screw isheld inposition by means of the H nuts 44 and 45 engageable, respectively, withthe upper and lower surfaces of the frame member 6 and which nuts'may'beemployed in a manner which is obvious to. adjust'the height of the screwmember 43. A bolt '46 is threaded into'the lower end of the screw 1member and is utilized to hold the bearing 36 between the head offthebolt and the 7 lower end "of said screw member so as to support themechanism including the arms 35 and 38 in proper position. Thus it willbe seen that by regulating the height ofthe screw member 43 the positionof the toggle mechanism and of'the plunger 16 maybe adjusted so that theextremity of downward movement of said plunger 16 may be-regulated inorder that the die will properly form the button.- The means forsupporting the ejectoroperating rod 34 so as to properly position itslower end for contact with the ejector 32 'die, a plunger carried bysaid frame for operating said d1e', means for applying'pressure to saidplungerincluding a supporting bearing, a plurality of pivotallyconnected toggle arms joiningsaid bearing with'said plunger, a screwmember adjustable in said i frame, a loolt'threaded into said screw memI ber longitudinally thereof and carrying said bearing in a fixedposition between thesame and said screw member," and me'ans-foradjustingthe screw member relative to the frame to alter the efiective' movementof said plunger. 1
